The Armstrong International VERIS Accelabar flow meter is a unique primary flow element that combines two differential pressure technologies to produce operating ranges never before attainable in a single flow meter. It is capable of generating high differential pressures for measuring gas, liquids, and steam at turndowns previously unattainable—with no straight run requirements.
The Accelabar consists of a unique toroidal nozzle design and a Verabar averaging pitot. The nozzle has a patented straight run “settling distance” that accelerates, linearizes, and stabilizes the velocity profile sensed by the Verabar. The Verabar, located within the nozzle, accurately measures and significantly increases the differential pressure output to increase the operating range (turndown). The Accelabar has a constant flow coefficient and produces an accuracy of up to ±0.50%.
The Accelabar can be used in extremely limited straight run piping configurations. The straight run is integral to the meter. The stabilization and linearization of the velocity profile within the throat of the nozzle eliminates the need for any upstream run.
The proven technology of the Verabar makes the Accelabar work. It accurately measures the flow rate within the nozzle. Its unique bullet shape, constant flow coefficient, solid one-piece construction, non-clog design, and signal stability make it the only design capable of producing the overall performance.
The Accelabar is a complete flow meter ready to install. It comes complete with single or dual transmitters depending on the turndown requirements.
